Yes, looks like it's changed to 4:3 again. When did this happen? It was still cropporama when I left at 9:50, so it changed some time between then and 10:45. Looked like the cropporama could have been in error looking at the "1974" DOG- it was elongated and outside the 4:3 safe zone.
At 10.25am it switched from 14:9 to 4:3, leaving the '1974' logo out of the frame. If that isn't bizarre enough, at 10.28 it literally 'walked' back into the picture!
The reason the news was not included is probably that Network Control would have done the cut to the news studio, whereas the weather was presented (bizarrely) from the election studio. The recording is most likely studio output and not network output.
